In treatment group, there was no progressive necrosis in stasis zone, and at 24 h post injury, capillary dilation, cell edema and inflammatory infiltration were lessened significantly. In control group, 2 wounds had progressive necrosis (accounted for 10% of the total). Cell edema, inflammatory infiltration and capillary thrombosis were serious, Until 72 hr post injury, cell edema did not subside and necrosis of the dermis worsened. 2. Pathological assessment of the stasis zone tissue: As compared with that in control group, in treatment group the dermis structure in stasis zone was intact and the collagenous fiber bundle was normal.
